AMD cpu + Elite K7S5A mobo

I have the above and the cpu keeps changing values on startup everynow and then.I've heard that there is a problem with these two together,is that true? What can i do about this problem , i don't want the kids going into the bios every time this thing happens .I'm using W98SE and the cpu is an XP1800+ , has anyone else got this problem .JACC

Have a look at the motherboard, Bottom left corner and their will be a model no. Something along the lines of: REV 1.1 or 1.3 if the former then they do tend to clash, if the latter I believe some people have successfully flashed the board to make them work together.
